Problems solved by technology

[0005] However, in the centrifugal spinning machine described in Patent Document 1, in order to rewind the yarn when the yarn is broken, the entire yarn unwinding member is raised and inserted into the inside of the tank, so there is a problem of increasing the size of the entire device. question

Embodiment approach 2

[0135] Next, the structure of the centrifugal spinning frame according to Embodiment 2 of the present invention will be described. Furthermore, in Embodiment 2, with Figure 1 to Figure 15 The reference numerals with the same reference numerals are the same or the same structural elements, and thus detailed description thereof will be omitted.

[0136] The structure of the centrifugal spinning frame according to this second embodiment is compared with that of the first embodiment in that the front end portion of the elongated member is elastically supported by the base end portion.

[0137] Figure 16 The outline of the elongated member 73 according to the second embodiment is shown. The front end portion 73a of the elongated member 73 is elastically supported by the base end portion 73b by a compression spring 73c. The compression spring 73c constitutes an elastic supporting member. The base end portion 73b of the elongated member 73 is supported by a fixed fulcrum E. As ...

Abstract

The invention provides a centrifugal spinning frame which can enable a structure for rewinding yarns to be smaller when the yarns are broken. The centrifugal spinning frame includes an elongated member (73) including a contact end portion (73a) contactable with an inner wall (22) of a pot (12), and a base end portion (73b) supporting the contact end portion (73b), an up-down movement actuator (76)adjusting a position of the contact end portion (73a) in a height direction to a yarn end position (28b) of a yarn (18) deposited on the inner wall (22), a guide member (40) holding the elongated member (73) in a direction that crosses a tilting direction of the elongated member (73) and guiding the elongated member (73), an elastic support member (47, 48) elastically supporting the contact end portion (73a) in the tilting direction, and a tilting movement actuator (78) tilting the elongated member (73) so that the contact end portion (73a) is placed in contact with the inner wall (22) of thepot (12).

Description

technical field [0001] The present invention relates to a centrifugal spinning frame, and more particularly to a centrifugal spinning frame having a structure for rewinding a yarn when a yarn is broken. Background technique [0002] As one of spinning frames, a centrifugal spinning frame using a cylindrical pot is known. In the centrifugal spinning machine described in Patent Document 1, a cylindrical bobbin is disposed coaxially with the yarn guide tube outside the yarn guide tube. In addition, the yarn is wound around the inner wall of the pot while twisting the yarn spun from the yarn guide bobbin to form a yarn cake, and then rewinding of the yarn to the bobbin is resumed. [0003] If the yarn is broken due to some reason during spinning, the yarn is lifted from the cake by bringing the blade of the yarn unwinding member into contact with the cake formed on the inner wall of the tank, thereby restarting the yarn Rewind to bobbin. [0004] Patent Document 1: Japanese P...
